Objective To investigate the significance of anti-SmD1 antibody and other auto-antibod- ies in systemic lupus erythematosus(SLE).Methods Forty-four SLE patients and 136 other rheumatic dis- eases patients were studied.The later group included Sj(?)gren's syndrome,undifferentiated connective tissue disease,ankylosing spondylitis,and rheumatoid arthritis.Immunoblotting was used to measure,the anti-SmD1 antibody,ANuA and anti-SSA60 000 antibody.ANA and anti-dsDNA were detected by indirect immunofluo- rescence,immunodotting was used to measure the anti-Sin antibody.Results The seropositive rate of anti- StuD1 was 47.7% in SLE patients.It was much higher than that of anti-Sm(P

Objective To analyze the antiangiogenic effect of stereotatic radiosurgery (SRS) in rat C6 gliomas using MR perfusion imaging(PWI) technique. Methods Twenty rats implanted with C6 glioma cells in the brain were randomly assigned into group A (without any therapy) and group B which underwent SRS therapy 4 weeks after implantation. PWI was performed to measure the regional cerebral blood volume (rCBV) and regional cerebral blood flow (rCBF) in tumor's region before therapy in all rats and 1 week later in group B. PWI sequence was applied pre-and post--inhalation of a mixture of 10% CO_2 and 90% air. rCBV and rCBF were analyzed. PaCO_2 and blood PH values were monitored before and aftermixed gas inhalation. All the MRI examination were car-ried out at a 3.0T magnet. The rats were sacrificed after MRI examination. Microvessel density (MVD) and number of mature ves-sels (with muscle layer) were measured histologically using immunohistochemical staining for factorⅧ and smooth muscle actin (SMA). PWI data, and pathological results were analyzed statistically. Results The size of tumors in group B remarkably de-creased with obvious necrotic area in the center 1 week after SRS therapy. PH value decreased and PaCO_2 increased significantly af-ter mixed gas inhalation. Blood gas data changes in group B were not significantly different from that in group A. The rCBV and rCBF of tumor's core in group B declined greatly after SRS treatment. The necrotic area was dark in rCBV and rCBF maps, that suggested no blood supply in this region. After therapy, the changing rate of rCBV and rCBF pre-and post-inhalation of gas in group B was greater than those in group A. The MVD of tumors in group B after treatment was sta-tistically less than that in group A. The number of SMA positively stained vessels in group B was nearly equal to that in group A. The percentage of SMA(+)/MVD in group B was significantly higher than that in group A. Conclusion SRS can inhibit the angiogenesis of rat C6 glioma, however vessels with smooth muscle cells are insensitive to SRS.

[Objective] To answer the following questions:① For Oncomelania snails collected two years apart from the same locality,has there been genetic divergence?②How much experimental error has there been in studying subsets of these populations? ③As this is an unstable population,what has the net effect been on Hardy-Weinberg equilibrium(Hwe)?[Methods] Allozymes were studied using horizontal starch gel electrophoresis.Data collected from numbers of experiments were conapiled.Data from each collection were divided into two equal subsets based on chronology of the experiments.Thirty-four loci were studied using 72 to 180 snails per subset.[Results] The mean number of alleles per locus ranged frcra 1.5～1.9.With each consecutive subset,the 96 polymorphic loci dropped from 38.2 to 17.6.The mean heterozygosity was very low:0.033 to 0.049 and not significantly different from Hardy-Weinberg expectations.Ten loci and 11 alleles exclusive to the first group were eliminated from the overall study reducing the number of polymorphic loci from 19 to 10.There were significant departures from Hwe at five loci having a substantial number of individuals for each allele.Nei's and Wright's D were 0.003±0.001 and 0.054±0.006 respectively.[Conclusion] ①There were significant errors seen primarily in the results scored' in the earliest experiments.②These earlier errors involving scoring difficult to resolve loci,and interpretation of rare alleles that were not found in later experiment had no significant effect on overall genetic distance.③The use of Wright's D for closely related populations is explained.Results with Nei's D indicated no significant difference among the four subunits; Wright's D yielded significant difference between the collections made two years apart,attributed to the annual flooding of the Yangtze River mixing snails from different localities.④ Major polymorphic loci were not in Hwe as predicted using the unstable population model.⑤One must study 25 or more individuals to find relatively rate alleles and study population genetics.

Objective To examine the distribution of flurbiprofen axetil in cerebral-spinal fluid (CSF) by determining the CSF concentration of flurbiprofen after iv administration. Methods Seventy-two ASA Ⅰ or Ⅱ patients of both sexes aged 18-75 yr weighing 54-82 kg undergoing spinal or combined spinal-epidural anesthesia for lower extremity or lower abdominal surgery were studied. Flurbiprofen axetil 1 mg/kg was injected intravenously.CSF 2 ml and venous blood 3 ml were obtained simultaneously every 5 min after iv injection for 45 min (T1-9 ) for determination of flurbiprofen concentration using high performance liquid chromatography, and the CSF/blood flurbiprofen concentration ratio was caculated. Results Flurbiprofen was not detected in CSF at T1,2 after iv injection in 3 and 4 patients. The CSF flurbiprofen concentration was significantly higher at T4-9, and CSF/blood flubiprofen concentration ratio higher at T5-9 than at T3 ( P ＜ 0.05). There was no significant difference in CSF flurbiprofen concentrations among T4-9 ( P ＞ 0.05 ) Conclusion Flurbiprofen is detected in CSF after iv injection, the CSF flurbiprofen concentration peaks at 20 min after iv injection and it lasts until 45 min after iv injection.

Objective　To explore the relationship of defense style and mental health in student of middle school. Method 203 middle student were investigated with Defense Style Questionnaire (DSQ) and Symptom Check List-90 (SCL-90). Results There were no significant difference for 4 factors of DSQ in man／female and advance middle school or not(P>0.05); there were significant difference for immature defense mechanism and middle type factor ,and conceal factor in high-symptom score team with that of low-symptom sore team(P<0.01) and it is positive-correlation with each factor-score and total score of SCL-90. Conclusion School and family need to pay attention to the higher correlation in the total score of SCL-90 with immature defense mechanism and middle type factor and conceal factor.

Objective To investigate the efficacy of ultrasound?guided iliohypogastric∕ilioinguinal nerve block and transversus abdominis plane block for analgesia after cesarean section. Methods Ninety parturients, aged 20-40 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective cesarean section, were divided into 3 groups ( n=30 each) using a random number table:con?trol group (group C), ultrasound?guided iliohypogastric∕ilioinguinal nerve block group (group IH∕II) and ultrasound?guided transversus abdominis plane block group (group TAP). In IH∕II and TAP groups, bilat?eral ultrasound?guided iliohypogastric∕ilioinguinal nerve block and transversus abdominis plane block were performed after surgery, respectively, with 0.5% ropivacaine 1.5 mg∕kg ( the maximal dose 100 mg) plus dexamethasone 5 mg for each side. All the patients received patient?controlled intravenous analgesia with morphine after surgery, and numeric rating scales scores at rest and during movement were maintained<4 within the 48 h after surgery. The cumulative consumption of morphine was recorded at 6, 12, 24, 36 and 48 h after surgery. The occurrence of adverse reactions such as nausea, vomiting, pruritus, over?sedation and respiratory depression was observed and recorded in the analgesic period. Results Compared with group C, the cumulative consumption of morphine was significantly decreased at each time point in IH∕II and TAP groups ( P<0.01) . Compared with group IH∕II, no significant change was found in the cumulative consumption of morphine at 6 and 12 h after surgery, and the cumulative consumption of morphine was sig?nificantly increased at 24, 36 and 48 h after surgery in group TAP ( P<0.05) . No nausea, vomiting, pru?
ritus, over?sedation and respiratory depression was found in IH∕II and TAP groups. Conclusion For par?turients, ultrasound?guided iliohypogastric∕ilioinguinal nerve block and transversus abdominis plane block both can provide analgesic efficacy after cesarean section, and the efficacy of the former one is better.
